LSI Corporation LSISASx36 (SAS) Expander

Description: The LSISASx36 is a 36-port 3 Gb/s Serial Attached SCSI (SAS) expander with an integrated ARM processor for Enclosure Management and extended SAS SMP functions. This provides large storage environments the ability to connect multiple targets and initiators through a switched device for scalability and fault-tolerant path redundancy to improve system reliability.
